vhost: do not destroy device on repeat mem table message

It doesn't make any sense to invoke destroy_device() callback at
while handling SET_MEM_TABLE message.

From the vhost-user spec, it's the GET_VRING_BASE message indicates
the end of a vhost device: the destroy_device() should be invoked
from there (luckily, we already did that).
